Both the 20.x and 21.x ISO's fail to boot on my Dell T7600.
I tried both DVD and USB stick versions, same failure. Unfortunately I didn't copy the message down, but this appears to be the Ubuntu "EFI" bug discussed on Tom's Hardware page today.
Fortunately I have a copy of the older ISO (which is not the "v .2" version).
(I know this is an Ubuntu issue, not a Studio issue, but I wished to warn those trying to install right now on older hardware.)
